7 Claims.

This invention relates to vacuum cleaners of the usual household floor-cleaning type embodying a motor-driven fan, suction-nozzle and dustbag assembly to which is pivotally connected a handle for propelling the cleaner over the floor.

The present invention has for an object to provide such a .vacuum cleaner with a lighting device which is so arranged and combined with the cleaner as to adequately illuminate the nozzle and the floor area adjacent thereto. Another object of the invention is to provide a vacuum cleaner with a lighting device which does not add to the overall height of the cleaner or constitute such a protuberance as to interfere with the use of the cleaner in corners, under beds, or around the legs of tables, chairs, or other articles of furniture.

Another object of the invention is to provide a vacuum cleaner with a lighting device which is well protected against damage by collision, or by a falling body or other cause.

A further object of the invention is to provide the device with a suitable reflector.

Still further, the invention has for an object to provide a vacuum cleaner with a lighting device which is simple in construction, easy and inexpensive to manufacture and assemble, and which is a material aid to the efiicient use of the cleaner under conditions where natural or other general illumination is inadequate.

With the above and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations, and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Fig. 1 is a side elevation of a domestic electric floor-type suction-cleaner embodying the invention. Fig. 2 is a front elevation of the cleanerframe and nozzle. Fig. 3 is a perspective view of the fan-motor removed from the fan-casing and showing the lamp-guard detached from the motor-frame. Fig. 4 is a perspective view of the motor-casing. Fig. 5 is a perspective view of the reflector. Fig. 6 is a vertical longitudinal section through the lighting device, and Fig. 7 is a section on the line 7-7, Fig. 6, with the lamp-bulb removed to show the lamp-base receptacle.

1 represents the ambulant frame of the cleaner which is mounted on wheels 2 and includes the fan-casing 3 having the down-turned suctionnozzle 4 and dust-discharge pipe 5 towhich is connected the dust-bag 6. Mounted on the fancasing 3 is the fan-motor including the motorframe '7 in which is journaled a fan-shaft 8 carrying the fan-blades 9. The usual tubular propelling handle 10 is pivotally connected at 11 to the frame 1. The motor includes the upright cylindrical motor-frame-enclosing casing 12 which is formed in the front side of its cylindrical wall with an opening 13 in the form of an outwardly convex window exposing the recessed or flattened portions 14 of the motor-frame 7 between which is the recessed motor-field frameportion 15.

Screwed to the flat seats 14 are the upstanding feet 16 of the tubular lamp-guard 1'? of heavywalled cast-metal construction. The lamp-guard 17 is cut away at its under side to provide an inverted trough-shaped protecting hood for the tubular lamp-bulb 18 and is closed at one end to provide a cylindrical chamber 19 in which the usual lamp-base receptacle 20 is secured by the screw 21. The guard-body 17 is provided at one side with a flat vertical seat 17' to fit against the flat seats 14- of the motor-frame; the attaching feet 16 constituting continuations of the seat 1'7. The current-supply circuit wires 22 for the lampreceptacle 20 may pass into the motor-frame '7 through the aperture 23 and may be connected in any desired manner to the usual current-supply cord- 24, the lamp being preferably controlled by a suitable switch 25 on the handle 10.

A polished sheet-metal reflecting liner 26 is fitted to the inner face of the hooded portion of the lamp-guard 17. The reflector 26 has a depending apron extension 27 adjacent the motor-frame '7 and below the guard 1'7.

The lamp is thus disposed entirely within the vertical dimension or height of the motor-body and does not add to the overall height of the cleaner. It is also well in rear of the cleanernozzle 4 and the shoulder 28 of the tam-casing, where it is protected from collision. The heavy and substantial hooded construction of the guard 1'7 further protects the lamp 18 from damage by collision orby a falling body. 1

By recessing the motor and disposing the lighting device partially within such recess, there is secured a desirable sturdiness of construction and freedom from interfering protuberances of any kind. The light is, as it were, a built-in light 5 and not an annoying attachment. The horizontal disposition of the tubular lighting device and its partial reception in the tangentially recessed cylindrical motor also contribute to the desirable results above pointed out.

Further, by recesing the light reflectorin' the front wall of a vertically arranged cylindrical motor frame so that light is directed outwardly" through the window 13 from radiating or reflect'ing means in such recess there is secured the advantages of maximum compactness with minimum protuberance of the lighting device and with maximum lateral spread or lateral distribution'of the light rays. as well as frontal distribution.

having a window in its front side in register with the recessed portion of the motor-frame, an. ambulant motor-driven suction device carrying said motor and including a forwardly extending suction noz'zle, a light reflector disposed at least partially within, said window and at least partiaily within the cylindrical contour of the motorframe at the recess therein, and an electric light on said cleaner closely adjacent said reflector.

2. A domestic floor cleaner having an ambulant wheeled frame including a fan-casing and a forwardly extending and down-turned I suction nozzle, an electric motor having a motor-frame, a fan-shaft journaled in said motor-frame with its axis upright, a. suction-fan mounted on the lower end of said fan-shaft within said fan-casing, a casing encompassing the motor-frame and having aconvex window at the front of said motor and above and in rear of said suction nozzle,'a light reflector disposed at least partially within said convex window, and an electric light carried by said cleaner closely in front of said reg flector. V

3. A domestic floor cleaner comprising an electric motor having a cylindrical frame with its axis upright and a motor shaft journaled therein; said cylindrical frame having a recess in its front" side, casing 'means encompassing the motorframe and having a convex window in its front 7 side in register with said motor-frame recess, an

ambulant motor-driven suction device carrying a said motor and including a forwardly extending suction nozzle, a light reflector received-at least partially within'said convex window and at least partially within the cylindrical contour of the ,motor-frame at the recess therein, and an electric light on said cleanerclosely in front of said re-I 4. The combination with a suction-cleaner fan-motor of upright cylindrical form having a recess in its-cylindrical wall, of an inverted open trough-shaped lamp-guard mounted in saidrece'ss and having one and closed to form,a cylindrical chamber, and a lamp-base-receptacle mountedin said chamber.

5. The combination with a suction cleaner fanmotor of upright cylindrical form having a recess in its cylindrical wall, of an open trough-shaped 1 lamp-guard mounted in said recess and having one end closed to form a cylindrical chamber,
